Question

3. If one angle of a parallelogram is 30° less than twice the smallest angle, then find
the measure of each angle​

Answer 1

Step-by-step explanation:

let smallest angle =x

then other angle = 2x - 30

sum of these adjacent angles = 180°

x + 2x- 30° = 180°

3x= 180°+30°

x=210°/3

x=70°

other angle = 110°

in a parallelogram opposite angles are equal under sum of adjacent angles equal to 180°

70°, 110°, 70°, 110° are required four angles of parallelogram.

Answer 2

Step-by-step explanation:

one angle of a parallelogram is 30° less than twice the smallest angle, then find

the measure of each angle
